CVE-2025-52519

Local disclosure and service interruption via issimian validation

Published Jan 5, 2026 · Updated Jan 5, 2026

Improper input validation in Samsung Exynos camera firmware allows local users to disclose information and interrupt service. The issimian device driver accepts user-space input without sufficient validation, but Samsung has not disclosed the affected request or validation error. Low privileges and local access are required; the reported effects are limited to information disclosure and denial-of-service interruption, with no integrity impact.
